What kind ENABKL of function is it?

Solution:

• What kind ENABKL of function is it?

  There are more information about the LCD control signal, for your reference.
  
  SHFCLK----shift clock or data clock.
  pixel clock for flat panel data.The signal name on TFT
  LCD panel side could be
  NCLK,CLK,CK,CX, or DCLK.
  
  FLM----first line mark or vertical sync.
  Flat panel equivalent of VSYNC. The signal name on TFT LCD panel
  side is Vsync.
  
  LP----latch pulse or horizontal sync.
  Flat panel equivalent of HSYNC. The signal name on TFT LCD panel
  sideis Hsync.
  
  M----M signal as display enable or display timing.
  The signal name on TFT LCD panel side could be ENAB,DE or DTMG.
  
  ENABKL----Enable backlight.
  Backlight is the light source of LCD panel and usually
  integrated in LCD.An LCD
  backlight inverter is required to drive backlight. Most
  inverter need +12V as power
  supply. An example of TFT LCD inverter input connector
  is as follows:
  
  Pin numberFunction pin1:Vin pin2:GND pin3:On/Off control
  pin4:VR pin5:GND
  
  Note: Vin is connected +12V power supply. On/Off control needs to be
  connected to
  ENABKL to control backlight ON/OFF. VR is the brightness
  control input. User can
  connect a potentiometer between VR and GND to control
  brightness of backlight, or
  short VR to GND for maximum brightness. The value of
  potentiometer can be
  selected according to the control sensitivity that user
  needs. The recommended value
  is from 1 ~ 5 kohm.
  The output signal of inverter is high voltage AC source.
